(Extra-axial Haematoma; Subdural Haemorrhage; SDH)

Definition

A hematoma is a collection of blood. A subdural hematoma develops in the space between the covering of brain (the dura) and the inside of the skull. This pool of blood can put pressure on the brain and cause a range of symptoms.

Causes

A subdural hematoma is most often caused by a head injury. The injury may be caused by traumas such as falls, car accidents, or physical abuse. It can also occur spontaneously.
